Order Status Helper

Summarize an order object for a support dashboard. The final summary should expose payment status, shipping status, item count, and whether the order needs attention.

Write these functions:

isPaid(order) should return true when payment.status is "paid".
hasShipped(order) should return true when shipping.status is "shipped".
getDeliveryMessage(order) should return a shipping message and include estimatedDelivery when the order has shipped.
needsAttention(order) should return true when the order is unpaid or has not shipped.
createOrderSummary(order) should return id, customerName, paid, shipped, itemCount, deliveryMessage, and needsAttention.

Sample checks:

const order = {  id: 'ORD-1001',  customer: {    name: 'Ava Stone',    email: 'ava@example.com',  },  payment: {    status: 'paid',  },  shipping: {    status: 'shipped',    estimatedDelivery: '2026-06-18',  },  items: [    { name: 'Notebook', quantity: 2 },    { name: 'Pen Set', quantity: 1 },  ],};console.log(createOrderSummary(order));console.log(isPaid(order));console.log(hasShipped(order));const pendingOrder = {  ...order,  payment: { status: 'unpaid' },  shipping: { status: 'processing', estimatedDelivery: '2026-06-18' },};console.log(needsAttention(pendingOrder));console.log(getDeliveryMessage(pendingOrder));

Expected output:

txt

{ id: "ORD-1001", customerName: "Ava Stone", paid: true, shipped: true, itemCount: 3, deliveryMessage: "Order shipped. Estimated delivery: 2026-06-18.", needsAttention: false }truetruetrueOrder has not shipped yet.

For itemCount, add item quantities instead of counting item rows.

Solution:

function isPaid(order) {  return order.payment.status === 'paid';}function hasShipped(order) {  return order.shipping.status === 'shipped';}function getDeliveryMessage(order) {  if (hasShipped(order)) {    return `Order shipped. Estimated delivery: ${order.shipping.estimatedDelivery}.`;  }  return 'Order has not shipped yet.';}function needsAttention(order) {  return !isPaid(order) || !hasShipped(order);}function createOrderSummary(order) {  let itemCount = 0;  for (const item of order.items) {    itemCount += item.quantity;  }  return {    id: order.id,    customerName: order.customer.name,    paid: isPaid(order),    shipped: hasShipped(order),    itemCount,    deliveryMessage: getDeliveryMessage(order),    needsAttention: needsAttention(order),  };}const order = {  id: 'ORD-1001',  customer: {    name: 'Ava Stone',    email: 'ava@example.com',  },  payment: {    status: 'paid',  },  shipping: {    status: 'shipped',    estimatedDelivery: '2026-06-18',  },  items: [    { name: 'Notebook', quantity: 2 },    { name: 'Pen Set', quantity: 1 },  ],};console.log(createOrderSummary(order));console.log(isPaid(order));console.log(hasShipped(order));const pendingOrder = {  ...order,  payment: { status: 'unpaid' },  shipping: { status: 'processing', estimatedDelivery: '2026-06-18' },};console.log(needsAttention(pendingOrder));console.log(getDeliveryMessage(pendingOrder));
